This invention relates to pyrophoric lighters and more particularly toportable lighters of this class which are especially suitable fordomestic purposes, for instance to light the gas of gas ranges, stoves,furnaces and the like.

It is an object of the invention to provide a pyrophoric lighter ofpistol shape in which the fuel reservoir is housed in the handle sectionof the pistol while the wick is ignited at the end of the relativelylong barrel section, in order to have the flame at a certain distancefrom the fuel reservoir to prevent any danger of explosion.

Another object is the provision of a simple, easily operable ignitionmechanism in which actuation of the trigger of the pistol shaped lighterbody will automatically ignite the wick.

' A form of construction of a pyrophoric lighter is illustrated in theaccompanying drawing in which,

Figure 1 is a viewv of the lighter in position of rest. a

Figure 2 shows the lighter with the wick ignited. b

Figure 3 is a view of the lighter with a side wall removed to show themechanism in the interior thereof. v

The represented 1i hter has the shape of a pistol with a hand e section1 and a relatively long barrel section 2. The handle section 1 containsthe fuel reservoir m. From the reservoir a wick tube n containing thewick 6 leads to the end of the barrel section. Normally the end of thewick is covered by means of a cover member a rotatably-mounted on thelighter body at c. The provision of the fuel reservoir m in the handlesection of the pistol and of the end of the wick at the end of thebarrel section has the advantage that the reservoir is relatively farawa fromthe flame when the lighter is ignited, t ereby preventing anydanger of explosion which could arise in cases where the fuel reservoiris situated too near the flame so as to become heated by the flame.

The mechanism for igniting the wick b and for moving the cover acomprises a hook e which engages a, segment f provided with 523,098, andin Germany March 17, 1980.

a gear 3 and rotatably mounted at 4. The hook e is pivotably mounted onthe trigger d which is adapted to swing about the pivot 5. This book eisjnormally held in enga ement with the recess 17 of the segment f ymeans of a spring6. To the trig er al is also hinged at 7 an arm 7:provider? with a rack 8. This rack is in mesh with a pinion Z keyed tothe pin 0, to which is connected the cover a. g is the friction wheelwhich is adapted to rotate together with a pinion 9 meshing with thegear 3 of the segment f. A flint stone 10 is applied against thefriction wheel 9 by means of a spring 11; the pressure exerted on theflint stone can be adjusted by means of a screw nut 12. v

In order to ignite the wick, the trigger d is pulled back so that therack 8 of the arm it actuates the pinion Z and the cover a is swung inopen position as shown in Figure 2. Simultaneously with the opening ofthe cover, the hook 6 acts upon the segment 7 and turns this segment inclockwise dlrection about the pivot 4 against the action of the spring18 which is put under tension. The hook e is provided with a cam surface5 which is adapt ed to cooperate with a cam surface h of the segment 7.When the'trigger d is near the end of its backward stroke the camsurface It comes into contact with the cam surface 2' and after apredetermined amount of rolling of one of these surfaces along-the otherthe hook e is depressed against the action of the spring 6 and falls outof enga ement with the recess 17 of the segment ment f then beingreleased, is suddenly pulled back in counterclockwise direction by thespring 13 and the gear 3 meshing with the pinion 9 produces a nickmovement of rotation of the friction w eel 9 whereby sparks are thrownfrom the flint stone 10 to the wick Z) and ignite this latter.

The cover a is held 0 en as long as the trigger is held in its ackwardposition. When the trigger is released, it is returned in its normalposition 'by means of a spring 0. The cover a-is-brought back in itsclosing position and extinguishes the flame of the wick, while the hooke sliding forwards, will be depressed by the projection 14 of thesegment The seg- 7 until it has passed this projection, wherethe toothedsegment, a spring acting on said upon the spring 6 will urg it again inense ent, and cooperating cam surfaces on gagement with the recess 1After this the said hook and on said segment. 1 lighter is again readyfor use.
